SLAPPA's patented d2 pockets are the ideal solution to storing your discs and disc covers together without having to hold on to the bulky and brittle jewel cases.     Each d2 pocket contains dedicated layered pockets for your disc and disc cover, which include a front windowed section for the disc cover and a fully-lined rear pocket for your disc.   d2 pockets not only save tons of space compared to traditional jewel cases (from 40% with a 40 CD case to over 700% with our 600 PRO CD case), they also make it easy to find the disc you're looking for with the disc cover artwork boldly displayed in the front pocket.
